If you hadn’t heard of MF Global, the New York investment house that burst into the headlines with its stunning collapse on Halloween, don’t feel too out of the loop. Jon Corzine, the top guy at the shop, hadn’t heard of MF Global until a week before he joined the firm in March of 2010.

You may remember Corzine as the brash man at the top of Goldman Sachs who lost his post after a power struggle that left him literally trying to run the investment company from a limousine parked outside Goldman headquarters in lower Manhattan. Talk about being kicked to the curb. Or you might recall him in his next role as U.S. senator, which post he tired of soon enough, leaving to run for governor of New Jersey. In that job, one might recall, Corzine hit the headlines for nearly being killed when the speeding police cruiser he was riding in crashed as it tried to get him to an event. He hadn’t bothered to fasten his seat belt.

And now comes MF Global.

Corzine’s new company, it now seems clear, was playing by the pre-crash rules, operating like the 2008 collapse of the housing market and all that followed had never happened.

MF Global was partying like it was 2007, risking not only the house’s money, but also its clients’ funds. (There are clear rules against mixing the two.)

MF Global will soon be most notable as the eighth-largest bankruptcy in our nation’s history. And Corzine, who was looking to get back into the game in a big way, will have yet another black mark against his name. There are doubtless those who are hoping against hope that the next line on the disgraced Corzine’s resume will be a list of serious charges for his dealings at MF Global.
